I Love Aural: Christina Aguilera - Vanity

I found this track at the very end of Christina Aguilera's new album Bionic. It should me her next because she owns it. An excerpt of my favorite lyric:

Mirror mirror on the wall
Hit up prince charming
Tell him give me a call
Never mind, screw him
Cause I found somebody better
Never mind, screw him
I'll make myself so much wetter
